SurFacCmd Surface Face Commands

This collection of tools is used to manipulate 3dFace objects. In the rightmost columns of the table, it indicated whether the tool works on Standard (4 point trapezium) or Triangular (3 point triangle) 3dFaces. Since CAD engines always use four points to define a 3dFace, in the case of triangular two points have the same coordinates.

Keyboard Command: SurFacCmd

Method Description S T
Boundaries: Generates polyline(s) that enclose (shrinkwrap) the selection set of 3dFaces. √ √
Direction: Set the direction of a selection set of 3dFaces to clockwise or counterclockwise. √ √
Edges:
  • Display Edges: Displays all the edges of all 3dfaces in the drawing, many of which may have been set to invisible. Simply issue a redraw to clear the temporary vectors.
  • Edges On: Turns on the edges of all 3dfaces in the drawing, many of which may have been set to invisible.
  • Edges Off: Turns off the edges of selected 3dfaces, they will no longer appear in the drawing unless SPLFRAME is set to 1 and a regeneration is issued.
 √ √
Elevation: Used to flatten or elevate the selected faces. Flatten prompts for a new elevation to flatten to, Elevate prompts for the vertical amount to raise or lower. √ √
eXplode: Explodes the selected faces to line objects with no duplication. √ √
Location: Creates a properly elevated point at the picked point, based on the 3dTriangle surrounding it. √
Normals: Draws line objects representing the face normals for triangular faces. This provides a visual indicator of the direction the triangular face points for rendering and modeling considerations. √
Offsets: Offsets triangular 3dFaces in the normal direction to create new 3dFaces. If you need the opposite direction simply enter a negative value for the offset distance. √
Point: Merges multiple face endpoints (within a specified radius) to a picked point. √ √
Restore: Restores 3dFace objects from lines forming logical faces (3, 4 points). √ √
Stats: Returns the area, slope and other properties of a selection set of 3dFaces. Note that slopes only reflect triangular faces. √ √
Subdivide: Subdivides selected 3dFaces into smaller units for smoothing. √
